Mine doesn't hang, but it can't be tipped over. It's a 10 gallon tote with lid, horizontal nipples placed on the side and near the bottom of the tote, and a stock tank deicer that is okay to use in plastic. Advantages are that it only needed filled once a week and it stayed thawed down to the -12 F we had last winter. To raise it up I put it on an old footstool from a chair. It's kept outside in the covered run to keep the moisture out of the coop.
You could try a hanging bucket with horizontal nipples. Some people use a bucket with heater or you could buy a bucket that has a heater built in. You'd have to have a lid for the bucket so that the chickens wouldn't accidentally fall in. Horizontal nipples seem to be less likely to freeze compared to vertical nipples.
